Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a radiator and an air conditioner. Background Art

[0002] As market demand continues to expand, users need air conditioners with greater cooling capacity. In order to provide the cooling capacity of the air conditioner, the input current of the compressor needs to be increased, which makes the operating frequency of the compressor higher. The greater the input current of the compressor, the greater the current carrying capacity of the compressor control module on the external unit mainboard, which causes the components (compressor control module) to generate too much heat, which will affect the service life of the compressor control module.

[0003] For heat-generating components (compressor control module) with large heat generation, considering the thermal conductivity of the heat-generating components themselves, the heat-generating components need to be packaged using an iron seal packaging method, and the electrical safety issues caused by direct contact between the heat-generating components and the radiator need to be resolved.

[0004] In the prior art, a refrigerant pipeline is used to introduce heat into the external unit mainboard for heat dissipation. However, the contact efficiency between the heat-generating components of the external unit mainboard and the refrigerant pipeline is low, and the heat dissipation and cooling effect is not as expected.

[0005] Moreover, the heat dissipation structure of the prior art will cooperate with the heat dissipation structure of the external mainboard and the heat generating components to form a fixed cooperation structure for better contact. If the heat generating components have problems or need to be repaired, it is difficult to disassemble and the components are easily damaged.

[0006] In summary, the heat-generating components in the prior art have the problems of poor heat dissipation and cooling effect and difficulty in disassembly. Summary of the invention

[0009] Furthermore, the heating component has a first surface and a second surface relative to each other, the first surface of the heating component is arranged toward the bottom of the placement groove, and the limiting pressure sheet abuts against the second surface of the heating component and applies a force toward the bottom of the placement groove.

[0010] Furthermore, a side wall of the placement groove is formed with an avoidance opening, and pins or connecting wires connecting the heat-generating component to the outside are inserted into the avoidance opening.

[0011] Furthermore, the diameter of the avoidance opening is larger than the outer diameter of the heat-generating component, and the heat-generating component can enter or leave the placement groove through the avoidance opening.

[0012] Furthermore, an insulating heat-conducting structure is connected between the first surface of the heat-generating component and the bottom of the placement groove.

[0013] Furthermore, the insulating heat-conducting structure is a ceramic sheet, a heat-conducting silica gel is arranged between the ceramic sheet and the bottom of the placement groove, and a heat-conducting silica gel is arranged between the ceramic sheet and the first surface of the heat-generating component.

[0014] Furthermore, the position-limiting pressing piece comprises a pressure section and a fixed section connected in sequence;

[0015] The pressure section is in abutment with the heat generating component, the fixed section is detachably connected to the heat dissipation body, and a bending angle is formed between the pressure section and the fixed section so that the pressure section has elastic pressure toward the bottom of the placement groove.

[0016] Furthermore, the fixing section is provided with screw holes, and the fixing section is connected to the surface of the heat dissipation body by screws.

[0017] Furthermore, the bending angle ranges from 120° to 170°.

[0018] According to another aspect of the present invention, there is provided an air conditioner comprising the above-mentioned radiator.

[0019] The present invention provides a placement groove on the heat dissipation body, and the heat generating component is arranged in the placement groove, so that shaking or vibration can prevent the heat generating component from being separated from the heat dissipation body, thereby ensuring the heat dissipation effect. At the same time, the limiting pressing plate abuts and limits the heat generating component, so that the heat generating component can be fixed in the placement groove, so that the heat generating component and the heat dissipation body can always maintain contact, ensuring that the heat dissipation body can continuously and stably dissipate heat for the heat generating component, thereby improving the heat dissipation and cooling effect. Moreover, the limiting pressing plate is detachably connected to the heat dissipation body, so that the maintenance personnel can directly remove the limiting pressing plate during maintenance, and then the heat generating component can be directly taken out from the placement groove, which is convenient and quick to disassemble, and also avoids the problem that the fixing structure is complicated and easily damages other components during the disassembly process.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0035] See also Figures 1 to 14As shown, according to an embodiment of the present invention, a radiator is provided for dissipating heat from a heat-generating component A. Taking a compressor control module as an example, the radiator includes a heat-generating body 10 and a limiting pressure piece 20. A refrigerant flows inside the heat-generating body 10. A placement groove 11 is provided on the heat-generating body 10. The heat-generating component A is arranged in the placement groove 11. The limiting pressure piece 20 is detachably connected to the heat-generating body 10. The limiting pressure piece 20 abuts against the heat-generating component A and limits the movement of the heat-generating component A.

[0036] The present invention provides a placement groove on the heat dissipation body, and the heat generating component is arranged in the placement groove, so that shaking or vibration can prevent the heat generating component from being separated from the heat dissipation body, thereby ensuring the heat dissipation effect. At the same time, the limiting pressing plate abuts and limits the heat generating component, so that the heat generating component can be fixed in the placement groove, so that the heat generating component and the heat dissipation body can always maintain contact, ensuring that the heat dissipation body can continuously and stably dissipate heat for the heat generating component, thereby improving the heat dissipation and cooling effect. Moreover, the limiting pressing plate is detachably connected to the heat dissipation body, so that the maintenance personnel can directly remove the limiting pressing plate during maintenance, and then the heat generating component can be directly taken out from the placement groove, which is convenient and quick to disassemble, and also avoids the problem that the fixing structure is complicated and easily damages other components during the disassembly process.

[0037] Preferably, the heating component A has a first surface and a second surface opposite to each other, the first surface of the heating component A is arranged toward the bottom of the placement groove 11, and the limiting pressing piece 20 abuts against the second surface of the heating component A and applies a force toward the bottom of the placement groove 11. Generally, the first surface and the second surface of the heating component A are the two opposite surfaces with the largest areas on the outer surface.

[0038] The heat exchange area between the first surface of the heating element A and the bottom of the placement groove 11 is more sufficient, and the heat dissipation effect is better. The limiting pressure piece abuts on the second surface, and the limiting pressure is more direct, which can effectively ensure that the first surface of the heating element always maintains the maximum heat exchange area. On the one hand, the fixed limiting effect is better, and on the other hand, the heat dissipation and cooling effect is improved.

[0039] Combination Figure 3 , Figure 4 and Fig.10 As shown, the side wall of the placement groove 11 is formed with an avoidance opening 12 , and the pins or connecting wires connecting the heat-generating component A to the outside are inserted into the avoidance opening 12 .

[0040] Since the heat generating component A (such as the compressor control module) needs pins or connecting wires to be connected to the outside (such as the PCB board), the position of the pins or connecting wires needs to be considered. The avoidance opening 12 of the present invention can first provide a space for placing the pins or connecting wires, thereby avoiding the problem of structural instability caused by the heat generating component A being installed too tightly. At the same time, the pins or connecting wires will not be subjected to abnormal forces, thereby avoiding unstable connections.

[0041] Further preferably, the diameter of the avoidance opening 12 is larger than the outer diameter of the heat generating component A, and the heat generating component A can enter or leave the placement groove 11 from the avoidance opening 12. In other words, the heat generating component A can be installed or removed from the avoidance opening 12. When the heat generating component A needs to be removed, it is only necessary to reduce the preload force of the limiting pressing piece or loosen the limiting pressing piece, and take the heat generating component A out of the avoidance opening 12 for maintenance, thereby simplifying the disassembly operation.

[0042] The avoidance opening 12 can not only be used for placing pins and routing wires, but can also be used as a loading and unloading path and loading and unloading space, thereby simplifying the disassembly steps and reducing the difficulty of disassembly.

[0043] Preferably, an insulating heat-conducting structure is connected between the first surface of the heating element A and the bottom of the placement groove 11. The iron-sealed heating element A (compressor control module) and the radiator are insulated by clamping the insulating heat-conducting structure in the middle, and the electrical appliance is safe and reliable. The insulating heat-conducting structure can be made of a variety of materials as long as it can conduct heat and insulate at the same time.

[0044] In this embodiment, the insulating heat-conducting structure is a ceramic sheet 30 , and heat-conducting silica gel is arranged between the ceramic sheet 30 and the bottom of the placement groove 11 , and heat-conducting silica gel is arranged between the ceramic sheet 30 and the first surface of the heat-generating component A.

[0045] See also Figure 5 The ceramic sheet 30 itself has insulation function and heat conduction effect, and the structure also satisfies the matching relationship between the placement groove and the heat-generating component A, and the heat conduction effect is ensured by setting the thermal conductive silica gel.

[0046] During the installation process, first apply thermal conductive silicone to the ceramic sheet and place it in the compressor control module to fit it with the radiator. Then apply thermal conductive silicone to the iron-sealed compressor control module and place it on top of the ceramic sheet to fit it. After installing the limit pressure plate (spring pressure plate), tighten the screws to clamp the ceramic sheet and the iron-sealed compressor module to the radiator.

[0047] Combination Figure 6 and Figure 7As shown, the limiting pressure piece 20 includes a pressure section 21 and a fixed section 22 connected in sequence; the pressure section 21 is in abutment with the heat-generating component A, and the fixed section 22 is detachably connected to the heat dissipation body 10. A bending angle is formed between the pressure section 21 and the fixed section 22 so that the pressure section 21 has elastic pressure toward the bottom of the placement groove 11.

[0048] Through the bending angle between the pressure section and the fixed section, the limiting pressure piece 20 forms an elastic structure after installation, that is, a spring pressure piece structure (which can be a Z-shaped structure). In this way, the limiting pressure piece can provide an elastic pressure effect through a simple structure and coordination, has a simple structure, occupies less space, and has a better heat dissipation effect.

[0049] Furthermore, the fixing section 22 is provided with a screw through hole, and the fixing section 22 is connected to the surface of the heat dissipation body 10 by means of a screw B. The present invention implements the fixation of the fixing section and the limiting pressing plate by means of screw connection. The advantage of screw connection is that when disassembly is required, the screw can be loosened to release the elastic pressure of the limiting pressing plate, so that the heating component A can be separated from the abutment of the clamping force. Maintenance personnel can directly disassemble the heating component A from the avoidance opening without disassembling all the structures, which greatly simplifies the operation. Since the number of heating components A and the number of placement slots are both multiple, the above-mentioned simplified operation is very necessary, which improves the maintenance efficiency and facilitates disassembly.

[0050] Preferably, the bending angle α has a value range of 120° to 170°. The bending angle α can be selected as 120° and 170°, and the bending angle can adjust the elastic pressure, and is most preferably 170°. The limiting pressing piece has an interference fit of 0.2 mm with the compressor control module to ensure that the compressor control module is completely fitted with the heat dissipation body.

[0051] Combination Figures 8 to 14 As shown, the structure of the heat dissipation body is introduced. The structure of the heat dissipation body can realize the heat dissipation of the refrigerant through various structures. This embodiment only introduces one of the structural forms. Other conventional technical means are also the methods defined by the present invention. Of course, in other embodiments not shown in the figure, the heat dissipation body can also be a main structure of an air-cooled radiator, and the specific structure will not be repeated.

[0052] like Figure 2 The heat dissipation body 10 is composed of a refrigerant inlet pipe 101, a refrigerant outlet pipe 102, an upper shell, and a base. The upper shell and the base form a shell structure with a refrigerant channel inside. The refrigerant enters the refrigerant channel from the refrigerant inlet pipe, passes through the internal refrigerant channel of the shell structure, and then exits from the refrigerant outlet pipe. The base has multiple sets of threaded holes for installation, support columns 103, and placement grooves.

[0053] Some threaded holes are used to fix the base and the upper shell, some threaded holes are used to fix the limit pressing plate on the heat dissipation body, and some threaded holes are used to fix other heating elements on the base. The support column 103 is used to be welded on the circuit board C to fix the heat dissipation body.

[0054] The present invention also provides an embodiment of an air conditioner, which includes the above-mentioned radiator.

[0055] The present invention provides a placement groove on the heat dissipation body of the circulating refrigerant, and the heat generating component is arranged in the placement groove, so that shaking or vibration can prevent the heat generating component from being separated from the heat dissipation body, thereby ensuring the heat dissipation effect. At the same time, the limiting pressure piece abuts and limits the heat generating component, so that the heat generating component can be fixed in the placement groove, so that the heat generating component and the heat dissipation body can always maintain contact, ensuring that the heat dissipation body can continuously and stably dissipate heat for the heat generating component, thereby improving the heat dissipation and cooling effect. Not only that, the limiting pressure piece is detachably connected to the heat dissipation body, so that the maintenance personnel can directly remove the limiting pressure piece during maintenance, and then the heat generating component can be directly taken out from the placement groove, which is convenient and quick to disassemble, and also avoids the problem that the fixing structure is complicated and easy to damage other components during the disassembly process.
